I'm not sure about salt water, but a little internet research seems to bring up that either aspirin made into a paste in water or baking soda in water will remove the chlorine from your hair.
I would think that salt water and sun might dry your hair out, so you might want to try a couple washes with baking soda to get the gunk out.....and maybe a less toxic clarifying shampoo if it doesn't work. And then follow with the vinegar rinse. In addition, I just found some information on using glycerine to help retain moisture in one's hair I haven't tried it yet.
I actually tried the baking soda wash and vinegar rinse today and it seemed to work surprisingly well after the pool. I'll let you know what happens in a couple of weeks, however!
Recipes I've found are below:
Hair Remedy Ingredients:

Mix up 1 part Baking Soda to 5 parts water. It's best to mix this before hand, and keep it in an old shampoo bottle. Mix 1 part Apple Cider Vinegar (Organic White Vinegar is fine, too) with 8 parts water. You can add some essential oils or herbs for a nice smell. Keep this mixture separate from the Baking Soda mixture.
Apply the Baking Soda mixture first. Shake well, and apply this to your scalp. Don't worry about getting it into the rest of your hair, this is just for your roots. Leave this in for a minute or two, and then rinse.
Apply the Vinegar mixture to your hair itself, and leave in for about 15 seconds. Rinse completely, and you are all done!
